The financial history books were fundamentally rewritten on December 15, 2025, as visionary entrepreneur Elon Musk officially became the first individual in human history to see his personal fortune exceed the astonishing threshold of $600 billion. The milestone was confirmed on a Monday afternoon, with his net worth rocketing to an estimated $677 billion, placing him hundreds of billions of dollars ahead of the world’s second, richest person.
This unprecedented surge in wealth was predominantly driven by the meteoric revaluation of his privately held aerospace company, SpaceX, which has become his single most valuable asset. Earlier in the month, SpaceX successfully completed a tender offer that effectively doubled its corporate valuation from the August figure of $400 billion to an immense $800 billion. Given Musk’s estimated 42 percent ownership stake in the firm, this single valuation event accounted for an instantaneous increase of approximately $168 billion to his personal fortune.
Musk’s substantial stake in SpaceX, valued at about $336 billion, has now definitively surpassed the value of his roughly 12 percent holding in the electric vehicle manufacturing giant, Tesla, which is estimated to be worth $197 billion.
Furthermore, his ventures in artificial intelligence are also adding considerable weight to his ballooning fortune. His artificial intelligence entity, xAI Holdings, is reportedly in the process of raising significant funds at a valuation of $230 billion. This figure represents more than double the $113 billion valuation Musk had previously cited in March when xAI was formed through a major merger with his social media platform, X. With approximately 53 percent ownership of xAI Holdings, his stake in this company is now valued at roughly $60 billion.

The sheer scale of this personal wealth is difficult to grasp. With a gap of roughly $425 billion separating him from the next wealthiest person, Musk is currently closer to becoming the world’s first trillionaire, a goal some investors predict he is on track to achieve, particularly if SpaceX proceeds with a rumored Initial Public Offering (IPO) in 2026 at a potential valuation of $1.5 trillion, than he is to losing his current standing as the richest individual globally. This new record firmly establishes a financial benchmark against which all future fortunes will be measured, cementing his place as an unparalleled figure in modern capitalist history.
